Compressibility and Tilting of Polyhedra within Sr2NiMoO6 at High Pressure
Ordered double perovskites (also known as elpasolites) have the general formula A2BBO6 where A is generally a rare earth metal or alkaline earth metal and where B and B are... -
Phase diagram of a switchable dielectric framework near the critical point
The family of hybrid Prussian blue analogues includes many electroactive materials, where organic cations moving within the pores of the cyanide framework cause unusual and... -
A high-temperature neutron powder determination of the phase transition and c...
Cu2ZnSnS4 (CZTS) is a solar cell material of great interest. However the material when fabricated, although of high symmetry, contains substantial defect concentration and a... -
Tracking spring-type motions in inorganic helices
Materials with helical and double helical structure motifs are prone to display fascinating spring-type behaviour, i.e. a shallow energy surface along the spring-axis in which... -
Thermal expansion and phase transition in magnesium sulfate trihydrate
A recent single-crystal study determined the crystal structure of MgSO4.3D2O, and discovered that a first-order phase transition occurs when the crystal is cooled below 245 K.... -
From small compositional changes to large distortions - a new relaxor energy-...
[BiZn2/3NbO3]x-[BaTiO3]1-x for x up to roughly 0.2, known as BZN-BT is a complex made from one of the most studied materials in the world, BaTiO3 (BT), doped with Bismuth Zinc... -
Non-magnetic impurities in a strong-leg spin ladder
Th S = ½ AF spin ladder is one of the most important models in quantum magnetism. While its properties throughout the (H,T)-phase diagram may be considered to be well understood... -
Thermoelastic Properties of Thermoelectric PbSe I HRPD
We propose to study the effect of pressure and temperature on the crystal structure and the elastic properties of lead selenide, an important material for conversion of waste... -
The icy-moon analogue of MgSiO3-perovskite: MgSO4.9H2O a high-pressure study
Mg-sulfate 11-hydrate (meridianiite) is decomposed by pressure to form Mg-sulfate 9-hydrate + ice, a process that will occur in the mantles of large icy planetary bodies and... -
Combined in-situ structural and hydrogen desorption/absorption studies of hyd...
The Li?N?H hydrogen storage system is one of the most promising candidates for hydrogen storage in vehicular applications and the addition of halide ions significantly increases... -
